EIETING DEVICE.

To all whom t may concern: Y

Be it knownlthat BERNARD E. SMITH, a citizen of the United States, `residing at Pond Creek, in the .county voflGranttand State of Oklahoma, haveV invented certain new and useful improvements in Lifting Devices, of which the following is a specification.

This invention relates to lifting devices designed for use in garages, sheds'and other places where motor vehicles-are stored when not in service, the object ofthe device being to lift the car oft1 the floor or ground so as to take all weight off the tires, and also to render the wheels, tires and other parts readily accessible for repairs, etc.

The invention has for its object to Aprovide a lifting device of fthe kind stated' which is simple in constructiomand efficient in operation, the device beingfautomatical'l-y operated by means of 4a novel combination -and arrangement of parts to be hereinafter described and claimed.

In order that the invention maybe better understood, reference is had tothe accompanying drawing in'` which- Figure 1 is a side elevation of the device partly in section and with the* parts in the position when the car is elevated, and Fig.2 is a plan view of the device. f

Referring specifically .tov the drawing, ,5 denotes two parallel longitudinal sills which are rigidly connected i-n laterally spaced relation by suitable cross braces 6, and mounted on the floor of the-shed or other building in which thecar is to be stored.

At its forward end each sill 5 vsupportsfan elevated horizontal rail 7 having at its forward end a raised portion 8a-nd at its rear end an incline 9, at the bottom of which latter is a Adepression 10. The rails ofthe "respective sills are'directly opposite eachother,

and they may be formed of flat metal bars suitably secured to the sills, and having upward bends at their ends, as shown in Fig. 1, to bring the tread portion a suitable distance above the sills. Intermediate their ends, the rails 'rest on braces 11 mounted on the sills, whereby they are prevented from sagging under the weight of the car.

At its rear end, each sill 5 supports an elevated horizontal rail 12, braced in the same manner as the rails 7, having an incline 13 at its rear end. These rear rails of the respective sills are also directly opposite each other.

speeification'of Letters Patent.

l Mounted foi` travel onthelrailslqand 12 is a wheeled lifting yframe composed of parallel longitudinal side `bars 14 connected at` rails 12. 'Qn top of the forward ends of the side bars 14 are rigidly mounted axle-sup porting members 18 having upstanding y y Patented Eenaieie- -iippiinationalea Merch 2o, 1915. serial No. 15,860. Y

abutments 19 in front. On top of the `'rear ends of theside bars 14 are rigidly mounted axle-supporting blocks 2Ol having top recesses 21 to accommodate the usual truss rods of the rear axle of the car.k

Alongside the sills 5, `on the outsidethere-V of, are guides for... properly centering the car with respect to the wheeled lifting frame. Thesev guidescoinprise boards 22 resting on the door or-the ground, and having upstanding boards v23 extendingy along their inner edges. The guidesare shown partly broken away in Fig. 1, and they are adjustably secured to the sills by lslotted angle brackets 24.

When the device is not in use'tlie lifting frame isin lowered position as shown dotted onto thev eleva-ted portions of the rails 7 and 12, these portions of the rails being at Vthe same level. On the boards 22, alongside the ilicli-nes 13, are mounted blocks 25,y having a double. incline. As the lifting frame travels forward withthe car,- and the wheels .17 mount the incline 13, the hind wheels of the car (shown dotted in Fig. 1 at 26) mount the blocks 25, and as soon" as the wheels 17 reach the elevated portion of the rails 12, the wheels 26 pass ofi" the blocks 25, the mo-' mentum of the car carrying the lifting frame forward a sufficient distance to leave the wheels clear of the ground. It will be noted that the bottom of the inclines 9 is onv a higher level than the bottom of the inclines y 13, and hence, when the lifting frame is in lowered position as shown dotted in Fig. 1,

the aXle support y18 is higher than the axle support 20. The front portion of the car is thereforelifted when the wheels 16 mountl the inclines 9, and when said wheels reach the top of the incline and continue forward on the elevated portion of the rails 7 by the momentum, the front wheels of the car (shown dotted at 26 in Fig. l) are also elevated above the ground. rIhe raised portions S of the rails 7 serve as stops to prevent the lifting frame from going forward too far. A locking device is also provided for preventing the lifting frame from rolling back to lowered position, said device comprising 'a latch levery 2'?v pivoted to the axle 28 of the wheels 16, and having a hook 29 intermediate its ends adapted to catch over a keeper bolt 30. n the front cross brace 6 ofthe sills is mounted a bracket 3l which carries the bolt 30. The free end of the lever -27 has a slot 32 in which works a pin 38 carried by an angle lever 34 which is pivotally supported by the bolt 80. Vhen the lifting frame is in lowered position, the levers 27 and 34 are in raised position, and as the frame advances, they drop forward, the hook 29 dropping over the bolt 80 and thus preventing the frame from going back to lower the car. When the car is to be lowered the lever 3st is swung upward, whereby, through its connection with the lever 27, the latter is released from the bolt 30, and the lifting frame is pushed rearward until the wheels thereof reach the inclines, whereupon they roll down the same and lower the frame until the wheels of the car again reach the ground, after which the car may be backed off the device. The axle-supporting blocks of the lifting frame must, of course, be properly spaced according to the spacing of the front and rear axles of the car. rIhe depressions prevent the lifting frame from going back too far, the wheels 1G seating in said depressions when the frame is down.

I claim:

l. A lifting device comprising` a support having front and rear elevated rails provided with inclines', the bottom of the inclines of the front rails being on a higher level than the bottom of the inclines of the rear rails, a lifting frame above the support,

front and hind wheels supporting said frame, said wheels being located to travel respectively on the front and rear rails and the inclines thereof, lifting inclines for the hind wheels of the vehicle located alongside the inclines of the rear rails, on the outside thereof, off which lifting inclines said hind wheels pass when the hind wheels of the lifting frame reach the top of the inclines of the rear rails, a pivoted latch lever carried by the forward end of the lifting frame, a keeper on the support for said lever, a lever pivoted to the support, and a connection between said lever and the latch lever for releasing the latter from its keeper and there after starting the lifting frame rearward toward the inclines of the rails.

' EZ. A lifting device comprising a support having 'front and rear elevated rails provided with inclines, the bottom of the in clines of the front rails being on a higher level than the bottom of the inclines of the rear rails, a lifting frame above the support, front and hind wheels sup1g orting said frame, said wheels being located to travel respectively on the front and rear rails and the inclines thereof, lifting inclines for the hind wheels of the vehicle located alongside the inclines of the rear rails, on the outside thereof, off which lifting inclines said hind wheels pass when the hind wheels of the lifting frame reach the top of the inclines of the rear rails, a pivoted latch lever carried by the forward endv of the lifting frame and having ahook, a bolt carried by the support and engageable by the hook, a lever pivoted on the bolt, and a connection between said lever and the latch lever for releasing the latter from its keeper and thereafter starting the lifting frame rearward toward the inclines of the rails.

In testimony whereof I affix my signature in presence of two witnesses.
